2 Claims.

This invention relates to soot catchers and has for its object andpurpose a means for arresting and collecting the soot from a furnace orthe like, as it travels through the smoke pipe or flue toward thechimney.

The means employed consists of a fan which is mounted in the smoke pipeand a soot receptacle comprising a vertical pipe connected to the flueabout midway between the furnace and the chimney. At the lower end ofthis pipe there is a cover which fits telescopically into the Verticalpipe and is held in place by a catch fastening. This cover, orreceptacle, which extends into the vertical pipe is the soot receptacle.

In the drawing:

Fig. 1 is an elevation partly in section of a furnace ue with sooteliminator attached which is also in section.

Fig. 2 is an enlarged top view of the fan with retaining ring insection.

Fig. 3 is a fragmentary section of the shaft bearing and fan mounting.

Fig. 4 is a sectional view slightly enlarged taken on lines I- of Fig.l.

Referring more particularly to the drawing, an ordinary flue I0 is shownmounted between a furnace II and the chimney I2, sai-d flue havingattached thereto a soot catcher or eliminating device consisting of ahollow body I3, a fan I4 mounted therein by means of a retaining ring I5within which the fan is supported rotatably on a shaft I6 and aremovable soot trap II supported within said hollow body I3.

The fan I4 consists of -a plurality of grooved F blades I8 attached byrivets or bolts I 9 to the vflanged ball bearing mounting 20, said fanrotating freely upon shaft I6 mounted through the bearing 2I.

The retaining ring I5 is provided with slots 22 and 23 in lugs 24 and 25respectively, small glass inserts 2t and 21 in said slots 22 and 23being used as bearing surfaces for the ends of shaft I6.

The retaining ring I5 is mounted by means oi screws or bolts 28 as nearthe top of the pipe I3 as possible so that the blades I8 of the fan I4may project as far up in the flue I0 as possible.

(Cl. 18S-77) The soot trap I1 has a pair of lugs 29 and 30 at opposedsides of the said trap and a handle 3| attached to the bottom surfacethereof, said trap conforming to the shape of the hollow body I3 whichmay be round, square, Octagon or oval. The trap I'I is inserted withinthe hollow body or pipe I3 through an oriiice 32 in the bottom surfaceof said body, in such way as to have the lugs 29 and 3G on the trap I'Iregister Vwith the slots 33 and 34 adjacent to said orice 32, the trapthen being rotated so that the lugs 29 and 30 will rest upon the innerflange-d surface of the body base.

In operation the suction draft indicated by feathered arrows from thefurnace II, cause the fan I4 to rotate anti-clockwise, drawing the sootfrom the flue I0 and causing it to drop down within the trap Il where itmay-be removed and destroyed.

It will thus be seen that I have provided a very simple, cheap andefficient soot catcher which requires Very little time to install, willt any existing furnace stack and will be free from any trouble, whilethe inclusion of the fan makes it positive in action.

I claim:

turned to rest upon the flange.

2. The combination with a substantially horizontal flue, of a Verticalpipe opening at its upper end into said flue, a rotary fan mounted inthe upper end of said pipe and having blades which project only partlyinto said flue during the upper part of their rotation, and a receptaclefor soot removably mounted in the lower end of the said pip-e, and aring fastened in the upper end of the vertical pipe and having bearingsfor the fan shaft.

JOSEPH BERINATO.
